摘要

A system for facilitating development of information material comprises a material generation apparatus and a digital assistant device. The material generation apparatus is operable to generate and store the information material on a data carrier with material location data identifying a location on the data carrier of the information material. The digital assistant device provides a wireless communications link with the material generation apparatus. The material generation apparatus is operable in response to a request communicated from the digital assistant device via the wireless communications link for material location data identifying an event represented within the information material to communicate the material location data of the material representing the event. Thus, an event observed by a user during the production of for example video material can be logged with the effect that the material location data identifying the event as represented on the data carrier can be used to facilitate subsequent navigation through the stored video material to reproduce the event. The facility for subsequent navigation is particularly useful if the data carrier is a linear medium, the reference location data including time code data. <IMAGE>
